Chapter 1: The Blonde That Was Lost To Time

The family of three were in the British Museum after hours. The Museum was closed and completely dark, but the curator and two security guards looked at the three, seemingly waiting for them on the front steps.

"Dr Kane!" The curator was a greasy little dude in a cheap suit. Carter, the elder of the two children, had seen mummies with more hair and better teeth than the curator. The little man shook Julius Kane's hand like he was meeting a rock star. "Your last paper on Imhotep- brilliant! I don't know how you translate those spells!"

"Im-ho-who?" Sadie, the younger of the two, muttered. She lived with her Grandparents in England, while Carter and his father travelled. Julius was only allowed two days with her, one in summer, once in winter. You would never have guessed she and Carter were related. Firstly, she had been living in England for so long, that she had a British Accent. Second was that, unlike Carter, she took after their mother, who was white, so Sadie's skin was much lighter than Carters. She had straight caramel-coloured hair, not exactly blonde but not brown, which she usually dyed with streaks of bright colours. That day it had red streaks down the left side. Her eyes were a deep sea blue. She was only 12, but was exactly the same height as Carter, which annoyed him to no end. She was chewing her gum, as usual, dressed for one of two days she spent with her father. She wore battered jeans, a leather jacket, and combat boots, like she was going to a concert and was hoping to stomp on some people. She had headphones dangling around her neck in case she got bored.

"Imhotep," Carter responded in an annoyed voice. "High priest, architect. Some say he was a magician. Designed the first step pyramid. You know." Carter resembled Julius a great deal. He was dark skinned, much like his father, with brown eyes. He had curly brown hair on his head, but it was very short. He held his suitcase at his side, and was dressed similarly to his father. He wore brown pants that reached just below his ankles, a brown shirt that was tucked in, along with a black tie. He wore a large white coat, like he was a junior professor.

"Don't know," Sadie said. "Don't care. But thanks."

Julius expressed his gratitude to the curator for hosting them on a holiday. He then put his hand on Carter's shoulder. "Dr Martin, I'd like you to meet Carter and Sadie." Julius Kane was a big guy, you wouldn't think a thing could scare him. He had dark brown skin like Carter's, piercing brown eyes, a bald head and a goatee, so he looked like a buff evil scientist. That day he wore his cash=mere winter coat and his best brown suit, the one he used for public lectures.

"Ah! Your son, obviously and-" The curator looked hesitantly at Sadie. "And this young lady?"

"My daughter," Julius told him.

Dr Martin's stare went temporarily blank. It didn't matter how open-minded or polite people thought they were, there was always that moment of confusion that flashes across their face when they realized Sadie was related to Carter and Julius. Both Carter and Sadie, unknown to the other, absolutely loathed that look. But over the years, the two had come to expect it.

The curator regained his smile. "Yes, yes, of course. Right this way, Dr Kane. We're very honoured!"

The security guards locked the doors behind them. They took their luggage, well Carter and Julius', but when one reached for Julius' workbag he made a tight smile.

"Ah no," he said as kindly as he could without sounding strained. "I'll keep this one."

The guards stayed in the foyer as the family of three followed the curator into the Great Court. It was ominous at night. Dim light from the glass-domed ceiling cast crosshatched shadows across the walls like a giant spiderweb. Their footsteps clicked on the white marble floor.

"So," Julius said, "the stone."

"Yes!" The curator said. "Though I can't imagine what new information you could glean from it. It's been studied to death- our most famous artefact, of course."

"Of course," Julius agreed. "But you may be surprised."

"What's he on about now?" Sadie whispered to Carter.

Carter didn't answer her. He had a sneaking suspicion about the stone they were talking about, but he had no idea as to why their father would drag the two of them on Christmas Eve to see it.

Carter wondered what Julius had been about to tell them at Cleopatra's Needle- something about their mother and the night she'd died. And why had he kept glancing around, as if he expected those strange people they'd seen at the Needle to pop up again? They were locked in a museum surrounded by guards and high-tech security. Nothing could bother them in there...at least he hoped.

They turned left into the Egyptian wing. The walls were lined with massive statues of the pharaohs and gods, but Julius Kane bypassed them all and went straight for the main attraction in the middle of the room. "Beautiful," he murmured. "And it's not a replica?"

"No, no," the curator promised. "We don't always keep the actual stone on display, but for you- this is quite real."

They were staring at a slab of dark grey rock about three feet tall and two feet wide. it sat on a pedestal, encased in a glass box. The flat surface of the stone was chiselled with three distinct bands of writing. The top part was Ancient Egyptian picture writing: hieroglyphics. The middle section...Carter had to rake his brain to remember what it was called: Demotic, a kind of writing fom the period when the Greeks controlled Egypt and a lot of Greek words got mixed into Egyptian. The last lines were Greek.

"The Rosetta Stone," Carter said, earning a nod from Julius.

"Isn't that a computer program?" Sadie asked.

Carter wanted to face palm and tell her how stupid she was, but Dr Martin cut her off with a nervous laugh. "Young lady, the Rosetta Stone was the key to deciphering hieroglyphics! It was discovered by Napoleon's army in 1799 and-"

"Oh, right," Sadie said. "I remember now."

She didn't really remember. She was just saying that to shut him up, but Julius had other ideas.

"Sadie," he said, "until this stone was discovered, regular mortals...er, I mean, no one had been able to read hieroglyphics for centuries. The written language of Egypt had been completely forgotten. Then an Englishman named Thomas Young proved that the Rosetta Stone's three languages all conveyed the same message. A Frenchman named Champollion took up the work and cracked the code of the hieroglyphics."

Sadie chewed her gum, clearly unimpressed. "What's it say, then?"

Julius shrugged. "Nothing important. it's basically a thank-you letter from some priests to King Ptolemy V. When it was first carved, the stone was no big deal. But over the centuries...over the centuries it has become a powerful symbol. Perhaps the most important connection between Ancient Egypt and the modern world. I was a fool not to realize its potential sooner."

His speech had lost Carter entirely, and apparently Dr Martin as well.

"Dr Kane?" He asked. "Are you quite all right?"

Julius breathed in deeply. "My apologies Dr Martin. I was just...thinking aloud. If I could have the glass removed? And if you could bring me the papers I asked for from your archives."

Dr Martin nodded. He pressed a code into a small remote control, and the front of the glass box clicked open.

"It will take a few minutes to retrieve the notes," Dr Martin said. "For anyone else, I would hesitate to grant unguarded access to the stone, as you've requested. I trust you'll be careful." He glanced at Carter and Sadie like they were troublemakers.

"We'll be careful," Julius promised.

As soon as Dr Martin's steps receded, Julis turned to his children with a frantic look in his eyes. "Children, this is very important. You have to stay out of this room."

He slipped his workbag off his shoulder and unzipped it just enough to pull out a bike chain and padlock. "Follow Dr Martin. You'll find his office at the end of the Great Court on the left. There's only one entrance. Once he's inside, wrap this around the door handles and lock it tight. We need to delay him."

"You want us to lock him in?!" Sadie asked, with no short amount of sudden interest and excitement. "Brilliant!"

"Dad," Carter said, "what's going on?"

"We don't have time for explanations," he said. "This will be our only chance. They're coming."

"Who's coming?" Sadie asked.

"He took Sadie by the shoulders. "Sweetheart, I love you. And I'm sorry...I'm sorry for many things, but there's no time now. If this works, I promise I'll make everything better for all of us. Carter, you're my brave man. You have to trust me. Remember, lock up Dr Martin. Then stay out of this room!"

Chaining the curator's door was easy. But as soon as they'd finished, the siblings looked back the way they'd come and saw a blue light streaming form the Egyptian gallery, as if their had had installed a giant lowing aquarium.

Sadie locked eyes with Carter. "Honestly, do you have any idea what he's up to?"

"None," Carter told her. "But he's been acting strange lately. Thinking a lot about Mom. He keeps her picture..." Carter didn't want to say anymore. Fortunately for him, Sadie nodded like she understood.

"What's in his workbag?" she asked him.

"I don't know. He told me never to look."

Sadie raised an eyebrow. "And you never did? God, that is so like you, Carter. You're hopeless."

Carter had wanted to defend himself, but just then a tremor shook the floor.

Startled, Sadie grabbed Carter's arm. "He told us to stay put. I suppose you're going to follow that order too?"

Carter thought that order was sounding pretty good, but Sadie sprinted down the hall, and after a moment's hesitation, Carter ran after her.

When the two of them reached the entrance of the Egyptian gallery, they stopped dead in their tracks. Julius stood in front of the Rosetta Stone with his back to them. A blue circle glowed on the floor around him, as if someone had switched on hidden neon tubes in the floor.

Julius had thrown off his over coat. His workbag lay open at his feet, revealing a wooden box about two feet long, painted with Egyptian images.

"What's he holding?" Sadie whispered to her brother. "Is that a boomerang?"

As stupid as it sounded for a grown man to be holding something like that, it was true. When Julius raised his hand, he was brandishing a curved white stick that did, indeed, look like a boomerang. But instead of throwing the stick, he thouched it to the Rosetta Stone. Sadie caught her breath. Julius began writing on the stone. Wherever the boomerang made contact, glowing blue lines appeared on the granite. Hieroglyphs.

It made no sense at all to Carter. How could he write glowing words with a stick? But the image was bright and clear, ram's horns above a box and an X.

"Open," Sadie murmured. Carter stared at her, because it sounded like she had just translated the word, which should have been impossible. Carter had been with their father for years, and he could only read a few hieroglyphs. They were seriously hard to learn.

Julius raised his arms. He chanted: "Woo-seer, i-ei." And two more hieroglyphic symbols burned blue against the surface of the Rosetta Stone. It appeared to be, from left to right, an eye with a thin throne facing the side on top, a man that looked to be in a sitting position with his knees pointing diagonally left facing the left. A feather with two stems, a feather with a single stem, and the bottom half of an X.

As stunned as Carter was, he recognized the first symbol. It was the name of the Egyptian god of the dead.

"Wo-seer," Carter whispered. He had never heard it pronounced that way, but he knew what it meant. "Osiris."

"Osiris come," Sadie said, as if in a trance. Then her eyes widened. "No!" She screamed. "Dad, no!"

Julius turnd in surprise. He started to say, "Children-" but it was too late. The ground rumbled. The blue light turned to a searing white, and the Rosetta Stone exploded.

When Carter regained consciousness, the first thing he heard was laughter- horrible, gleeful laughter mixed with the blare of the museum's security alarms.

Carter felt like he had just been run over by a tractor. He sat up slowly, dazed, and spat a piece of the Rosetta Stone out of his mouth. The gallery was in ruins. Waves of fire rippled in the pools along teh floor. Giant statues had toppled. Sarcophagi had been knocked off their pedestals. Pieces of the Rosetta Stone had exploded outwards with such force that they'd embedded themselves in the columns, the walls, the other exhibits.

Sadie was passed out next to Carter, but she looked unharmed. He shook her shoulder, and she grunted. "Ugh."

In front of them, where the Rosetta Stone had been, stood a smoking, sheared-off pedestal. The floor was blackened in a starburst pattern, except for the glowing blue circle around their father.

He was facing their direction, but he was definitely not looking at them. A bloody cut ran across his scalp. He gripped the boomerang tightly.

To his right, strangely, was a young man, who appeared to be unconscious. Carter vaguely noticed that he had golden blonde hair, that seemed to quiver oddly in the light breeze that went through the building. He couldn't see his face however.

Something stood between Julius and his two children. At first, Carter could barely make it out- just a flicker of heat. But as he concentrated, it took on a vague human form- the fiery outline of a man.

He was taller than Julius, and his laugh cut through Carter like a chainsaw.

"Well done," he said to Julius. "Very well done, Julius."

"You were not summoned!" Julius' voice trembled. He held up the boomerang, but the fiery man flicked one finger, and the stick flew from Julius' hand, shattering against the wall.

"I am never summoned, Julius," the man purred. "But when you open a door, you must be prepared for guests to walk through."

"Back to the Duat!" Julius roared. "I have the power of the Great King!"

"Oh, scary," the fiery man said with amusement. "And even if you knew how to use that power, which you do not, he was never my match. Now you will share his fate."

Carter could not make sense of anything, but he knew that he had to help Julius. He tried to pick up the nearest chunk of stone, but he was so terrified that his fingers felt frozen and numb. His hands were useless.

Julius shot him a silent look of warning: Get out. Carter realized he was intentionally keeping the fiery man's back to them, hoping Sadie and he would escape unnoticed.

Sadie was still groggy. Carter managed to drag her behind a column, into the shadows. When she started to protest, Carter clamped his hand over her mouth. That woke her up. She saw what was happening and stopped fighting.

Alarms blared. Fire circled around the doorways of the gallery. The guards had to be on their way, but Carter wasn't sure if that was a good thing for them.

Julius crouched to the floor, keeping his eyes on his enemy, and opened his painted wooden box. He brought out a small rod like a ruler. He muttered something under his breath and the rod elongated into a wooden staff as tall as he was.

Sadie made a squeaking sound. Neither of them could believe their eyes, but things only got weirder.

Julius threw his staff at the fiery man's feet, and it changed into an enormous serpent- ten feet long and as big as Carter- with coppery scales and glowing red eyes. It lunged at the fiery man, who effortlessly grabbed the serpent by its neck. The man's hand burst into white-hot flames, and the snake burned to ashes.

"An old trick, Julius," the fiery man chided.

Julius glanced at his children, practically screaming at them to run with his look. Part of Carter refused to believe any of it was real. He thought perhaps he was unconscious, having a nightmare. Next to him, Sadie picked up a chunk of stone.

"How many?" Julius asked rather quickly, trying to keep the fiery man's attention. "How many did I release?"

"Why, all five," the man said, as if explaining something to a child. "You should know we're a package eal, Julius. Soon I'll release even more, and they'll be very grateful. I shall be named king once more!"

"The Demon days," Julius said. "They'll stop you before it's too late."

At the word 'Demon' the blonde boy began to stir, as what appeared to be energy danced along his body. However the fiery man did not notice.

The fiery man laughed. "You think the House can stop me? Those old fools can't even stop arguing among themselves. Now let the story be told anew. And this time you shall never rise!"

The fiery man waved his hand. The blue circle at Julius' feet went dark. He grabbed for his toolbox, but it skittered across the floor.

"Goodbye, Osiris," the fiery man said. With another flick of his hand, he conjured a glowing coffin around Julius. At first it was transparent, but as he struggedled and pounded against its sides, the coffin became more and more solid, a golden Egyptian sarcophagus inlaid with jewels. Julius caught his son's eyes one last time, and mouth the word Run! before the coffin sank into the floor, as if the ground had turned to water.

"dad!" Carter screamed.

Sadie threw her stone, but it sailed harmlessly through the fiery man's head.

He turned, and for a single, terrible moment his face appeared in the flames. What they saw made no sense. It was as if someone had superimposed two different faces on top of each other- one almost human, with pale skin, cruel, angular features and glowing red eyes, the other like an animal with dark fur and sharp fangs. Worse than a god or a wolf or a lion- some animal neither had seen before. The red eyes stared at them, and they both knew they were going to die.

Behind the siblings, heavy footsteps echoed on the marble floor of the Great Court. Voices were barking orders. The security guards, maybe the police- but they'd never get there in time.

The fiery man lunged at the two. A few inches from Carter's face, something shoved him backwards. The air sparked with electricity. The amulets around their necks grew uncomfortably hot.

The fiery man hissed, regarding Carter more carefully. "So...it's you."

The building shook again. At the opposite end of the room, part of the wall exploded in a brilliant flash of light. Two people stepped through the gap- the man and the girl they'd seen at Cleopatra's Needle, their robes swirling around them. Both of them held staves.

At that point, the red energy that was swirling around the blonde on the ground shot into his body. The blonde slowly stood up, looking at the fiery man with calm, but dangerous cerulean blue eyes. He appeared to be 14. He wore what looked like a headband with a meal plate on it: a whirlpool symbol engraved into it. Three whisker marks adorned each of his cheeks, and he stood proud. He wore a pure white cloak that covered his entire body, so neither Sadie nor Carter knew if he was wearing anything underneath.

Sadie blushed at his appearance. Carter looked grateful, but also afraid slightly, because of the fiery man and girl that had just entered looked at the blonde in confusion. He opened his mouth, and spoke with a voice that sounded hardened by war...not a voice that someone who looked 14 should have. "Leave, before I show you how I earned the title 'Slayer of the Ninth Hell.'" The blonde ordered. The man's eyes widened, as if in realization.

The fiery man- Set- turned and his eyes widened upon seeing the blonde. He took a step back, a small smirk on his lips, then looked at Carter and snarled. "Soon, boy."

Then the entire room erupted into flames. A blast of head sucked all the air of out Sadie, Carter, and the blonde's lungs. The blonde collapsed in front of Sadie and Carter, while the two crumpled to the floor.

The last thing Carter could remember, was the man with the forked beard and the girl in blue were standing over the three of them. They heard the security guards running and shouting, getting closer. The girl crouched over Carter and drew a long curved knife from her belt.

"We must act quickly," she told the man.

"No," he said with some reluctance...and a little fear. His thick accent sounded French. "We must be sure before we destroy the children...and this 'Slayer Of The Ninth Hell' must not be harmed, or we are all doomed."

Carter slowly closed his eyes, and drifted into unconsciousness.
